Description

Guiding device for dental implantation operation

Technical Field

The application relates to the technical field of dental implantation, in particular to a dental implantation operation guiding device.

Background

Modern dental implant is an emerging discipline which is vigorously developed starting from the osseointegration theory proposed in the 60 th century. Through research, the bone-combining principle of pure titanium with good biological and bone tissue compatibility characteristics becomes the most basic theory for guiding the research and development of modern plantation. Therefore, the dental implant, namely the vertebral body which is designed to be similar to the shape of a tooth root by using pure titanium, can be implanted into the alveolar bone of the tooth-missing area to generate good bone combination with bone tissue; after the dental crowns are manufactured on the implant in the later period, the dental crowns can bear corresponding chewing force, the functions and the attractiveness are well recovered, and the dental crowns are the preferred restoration mode of the missing teeth.

Judging whether the dental implant surgery is successful or not, wherein the key point is the implantation position, direction and depth of the dental implant. The unstable factors such as positioning deviation, inaccurate entering depth and swinging in the direction can possibly cause perforation of the side wall of an intraoperative alveolar bone, damage of the adjacent tooth root, damage of a mandibular nerve tube, penetration of a maxillary sinus and other accidents, cause poor initial stability, cause difficulty in subsequent repair of a superstructure, and are more likely to cause poor prognosis and even implantation failure.

Doctors in various countries try to guide the dental implant surgery by means of various methods for precisely positioning the fixed-point positioning, depth positioning and guiding templates. Initially, the use of conventional surgical guide plates was attempted, but the positioning accuracy was insufficient, and the restriction on the opening degree was large, and it was difficult to obtain the ideal position and direction, and the method was mainly applied to the operation of guiding the implant implantation or the implantation position of a few teeth missing, which had less strict requirements. CT is a major breakthrough in the early radiodiagnosis of the 70 th century, axial, coronal and sagittal plane fault data are recombined through CT, multilayer cross section fault reconstruction panoramic images are carried out, so that the method becomes the most ideal radiographic inspection technology for oral cavity planting at present, the radiation dose required by the initial CT technology is very large, scattering artifacts can be generated by metal, the data can be exported and imported by usually needing third party software, the instrument is high in price, cone Beam CT (CBCT) is a three-dimensional imaging technology developed at the end of the 90 th century, the CBCT replaces helical CT scanning of a fan beam by three-dimensional cone beam X-ray scanning, the obtained direct data are two-dimensional data, and the three-dimensional images are obtained after reconstruction, so that the metal artifacts are small and the accuracy of the recombined data is high. The advent of CBCT has thoroughly changed the history that traditional oral maxillofacial radiology equipment can only provide two-dimensional images, can three-dimensionally scan the maxilla and mandible structures, simultaneously utilizes comprehensive computer application technology (CAD/CAM) developed in the 60 th century to carry out aided design and three-dimensional reconstruction to design a digital surgical implant guide plate.

In the dental implant operation, the implant hole needs to be drilled for a plurality of times to reach the implant requirement of the implant. The dental implant drill bit is respectively as follows according to the use sequence: pilot, pioneer, reamer, etc. Traditional dental implant guiding modes are mainly divided into two types: single-guide single-sleeve guided planting and multi-guide multi-sleeve multi-stage guided planting. The sleeves of the two are fixed on the circular base of the guide plate in an interference fit mode, and cannot fall off or be replaced in operation. The single guide plate and the single sleeve are only used for guiding the first drilling, and the subsequent drilling is completed by the operation experience of a doctor, so that the planting precision is greatly reduced. The multi-guide-plate multi-sleeve is used for guiding drilling holes by manufacturing planting guide templates with the same shape and matching with sleeves with different inner diameters, and the drill bit of the corresponding hole drill is guided by replacing the templates during operation. Therefore, the material is wasted, and the positioning template is required to be detached and arranged for many times during the operation, so that a large positioning error is easy to generate, and the accuracy of the implantation of the implant is affected.

The problem that the sleeve used by most existing planting guide templates cannot realize multi-stage drill guiding due to the fact that the sleeve is fixed on the template is solved by the Nobel guide planting system in a double-layer sleeve mode. The double-layer sleeve is divided into an inner layer and an outer layer, the outer layer is fixed on a guide plate in an interference fit manner like a common sleeve, and the inner layer sleeve is placed on the inner side of the outer layer sleeve and is connected in a clearance fit manner. The inner sleeve is a series of guide barrels with the same outer diameter and different inner diameters, and the multi-stage drill bit can be guided only by replacing the inner sleeve with different apertures during operation. However, because the inner sleeve and the outer sleeve are connected only through the gaps and have no fixing mode, the inner sleeve is easy to rotate along with the drill bit when the operation is carried out, and the problems of shaking and the like are caused by the gaps when the drill bit moves, so that the precision of the planting holes is not beneficial to guarantee. While SurgiGuide templates are implemented by making a series of pilot tunnel templates of different diameters, which is currently the most common method. Because when the drill bits with different diameters are guided, the corresponding guide tunnel templates are required to be selected, the clinical operability is poor, the secondary positioning error exists, and the manufacturing cost of the series of templates is high.

In summary, the dental implantation equipment in the related art is all cup jointed on the drill bit through deflector or guide sleeve class guider and directly led the drill bit, consequently need use the guider of different diameters to the drill bit of different diameters, can influence positioning accuracy when changing guider, influences the operation effect.

The dental implantation equipment in the related art is sleeved on the drill bit through the guide plate or the guide sleeve type guide device to directly guide the drill bit, so that the guide devices with different diameters are required to be used for the drill bits with different diameters, and the positioning accuracy and the operation effect are influenced when the guide devices are replaced.

To solve the above-mentioned technical problems, as shown in fig. 1 to 6, the present embodiment provides a dental implant operation guiding device, including: a base 21, an auxiliary planting guide rail assembly 22 and a planting machine head 1; wherein, the liquid crystal display device comprises a liquid crystal display device,

the base 21 is used for being installed in an oral cavity, and planting holes 211 corresponding to planting sites are formed in the base 21;

the auxiliary planting guide rail assembly 22 comprises a guide rod 221, the guide rod 221 is arranged on the base 21, a drill bit hole 11 is formed in the planting machine head 1, and the drill bit hole 11 is used for installing a planting drill bit;

the planter head 1 is also provided with a guide assembly 100, the guide assembly 100 is provided with a guide hole, the guide hole is matched with the guide rod 221, and the linear movement direction of the planter head 1 is limited to the axial direction of the guide rod 221 through the matching of the guide hole and the guide rod 221.

In this embodiment, the dental implant surgery guiding device mainly consists of a base 21, an auxiliary implant guide rail assembly 22 and an implant head 1, wherein the base 21 can be installed in the oral cavity as a fixed base, and in particular can be installed on teeth. The base 21 may be a digitally produced (e.g. 3D printed) resin or metal implant guide having an inner and outer contour matching the contours of the patient's teeth, which may be directly sleeved on the patient's teeth during use, and which may be fixed to the alveolar bone with a fixture, one base 21 covering several teeth. Planting holes 211 are formed in advance on the base 21 according to the needed planting points, and the planting holes 211 correspond to the planting points of the teethridge up and down after the base 21 is installed. The planting hole 211 is a circular hole, which is favorable for the drill bit to drill in, and the diameter of the planting hole 211 is constantly larger than that of the drill bit, so the drill bit can be universally used for drill bits with any diameter, the drill bit can rotate in the through hole without resistance, and the physiological saline for cooling can also enter an operation area more easily for cooling.

The auxiliary planting guide rail assembly 22 is mainly used for guiding the drilling direction of the drill bit, and in this embodiment, is mainly composed of a guide rod 221, the guide rod 221 and the base 21 are in a detachable structure, and the guide rod 221 can be installed on the base 21 during use. The upper end of the guide bar 221 extends a certain length out of the upper surface of the base 21. The length of the guide bar 221 can be designed differently for planting at different positions, and is mainly adjusted according to the opening degree.

The planter 1 in this embodiment is the same as the planter 1 in the related art in the power system, and only its external configuration is adjusted. In order to guide the planter head 1, the planter head 1 of this embodiment is provided with a guide assembly 100, and the guide assembly 100 is provided with a guide hole matched with the guide rod 221. The middle part of the planter head 1 is provided with a drill bit hole 11, and a planter drill bit can be arranged in the drill bit hole 11 and driven to rotate by a power system in the planter head 1. When the planter is used, the planter head 1 can be sleeved on the guide rod 221 by using the guide hole, and the gap between the guide hole and the guide rod 221 is smaller, so that the linear movement direction of the planter head 1 can only be the axial direction of the guide rod 221.

Since the drill bit is mounted on the planter head 1 and drills along with the linear movement of the planter head 1, the linear movement guide of the planter head 1 is realized through the cooperation of the guide rod 221 and the guide hole in the embodiment, and the drilling guide of the drill bit is further realized. When a different drill bit is replaced on the planter head 1, the drill bit can still be guided by the cooperation of the guide rod 221 and the guide hole. Therefore, the multi-stage drill bit guiding device has the advantages that the multi-stage drill bit guiding device is used for guiding the drill bit, guiding is not required to be readjusted after the drill bit is replaced, the technical effect of positioning accuracy is improved, and the problems that in the related art, the dental implant equipment directly guides the drill bit through the guide plate or the guide sleeve type guiding device which is sleeved on the drill bit, the guiding devices with different diameters are required to be used for the drill bit with different diameters, positioning accuracy is affected when the guiding devices are replaced, and the operation effect is affected are solved.

Since the linear movement of the planter head 1 is limited by the guide rods 221, in order to make the planter head 1 uniformly stressed during the movement, as shown in fig. 2 to 6, the auxiliary planting guide rail assembly 22 in this embodiment includes at least two guide rods 221, the guide rods 221 are symmetrically distributed on two sides of the planting hole 211, and the guide rods 221 are kept parallel;

similarly, the guide assembly 100 includes at least two guide holes symmetrically disposed on either side of the drill hole 11.

As shown in fig. 3, the auxiliary planting rail assembly 22 has two structural forms, one of which is a structure having only the guide bar 221. In the case where the tooth-missing gap is insufficient for installing the guide bar 221 with the base 223 and is limited by the opening degree, the guide bar 221 alone is selected to be placed on the buccal tongue/palate side of the alveolar ridge, and is supported and retained by the base 21 from the mucous membrane, so that the application range of the design can be increased, and the length of the drill bit can be fully utilized.

With respect to this structure, in order to facilitate the installation and the removal of the guide bar 221 on the base 21, in this embodiment, an installation hole is formed on the base 21, and the lower end of the guide bar 221 is inserted and fixed in the installation hole. Preferably, the mounting hole is a blind hole, in order to avoid the guide rod 221 rotating after being mounted, in this embodiment, the lower part of the guide rod 221 is provided with a fixing pile 224, the fixing pile 224 and the guide rod 221 can be in an integrated structure, a clamping groove corresponding to the clamping portion 225 is formed in the outer side of the mounting hole of the convex clamping portion 225 on the annular side of the fixing pile 224, the fixing pile 224 is spliced and fixed in the mounting hole, and the clamping portion 225 is clamped in the clamping groove to limit the rotational freedom degree of the fixing pile 224. The clamping portions 225 may be provided in plurality and uniformly distributed along the circumferential direction of the fixing piles 224, or may be provided on one side of the fixing piles 224.

As shown in fig. 2, another structural form of the auxiliary planting rail assembly 22 is a form in which a base 223 and a guide bar 221 are combined.

Specifically, the auxiliary planting guide rail assembly 22 further includes a base 223, the guide rod 221 is disposed on an upper end surface of the base 223, and the base 223 is detachably embedded in the planting hole 211. Taking the planting hole 211 as a circular hole as an example, the base 223 is provided with a circular ring structure, the outer diameter of the base 223 is equal to the inner diameter of the planting hole 211, and a through hole is formed in the middle of the base 223. The diameter of the through hole is still constantly larger than the diameter of the drill bit. Therefore, the auxiliary planting guide rail assembly 22 can be commonly used for drills with any diameter, the drill can rotate in the through hole without resistance, and the physiological saline for cooling can enter an operation area more easily for cooling. The drill bit of the planter head 1 reaches the corresponding planting site through the through hole of the base 223.

The base (base one) used when the auxiliary planting rail assembly is adopted is different from the base (base two) used when the auxiliary planting rail assembly including only the guide rod in the above-described embodiment is adopted. The planting hole of the first base is matched with the shape of the base, the diameter of the through hole of the base is equal to that of the planting hole of the second base, and the first base or the second base can be designed according to the auxiliary planting guide rail component.

In the two auxiliary planting rail assemblies 22, the distance between the two guide rods 221 is kept uniform, and the diameters of the guide rods 221 are also kept uniform, so that both structures can be applied to the planting head 1 in the present embodiment as shown in fig. 6.

In order to prevent the base 223 from rotating in the planting hole 211, as shown in fig. 2, the lower end of the base 223 in the present embodiment has a protruding positioning portion 222, the positioning portion 222 is configured as a polygonal structure, the lower portion of the planting hole 211 has a positioning hole matching with the positioning portion 222, and the positioning portion 222 is inserted into the positioning hole to limit the rotational freedom of the base 223. The positioning portion 222 may have a hexagonal or pentagonal structure, and the positioning portion 222 and the positioning hole cooperate to prevent the base 223 from further rotation after being mounted in the planting hole 211.

When the auxiliary planting guide rail assembly 22 with the base 223 is used for guiding the planting machine head 1, the upper end face of the base 223 can extend out of the upper end face of the base 21, and the extending length is determined according to the drilling depth of the drill bit. The upper end surface of the base 223 is used for propping against the lower end surface of the guide assembly 100 to limit the maximum drilling displacement of the planter head 1, when the lower end surface of the guide assembly 100 is propped against the base 223, the planter head 1 cannot move down further, so that the drill bit cannot drill further, and the drilling depth of the drill bit is accurately controlled.

When the planter head 1 is guided using the single guide bar 221, an additional depth controller is required to control the depth of penetration of the drill bit. Therefore, as shown in fig. 4, the auxiliary planting rail assembly 22 in this embodiment further includes a depth control ring 23, a socket hole 231 corresponding to the guide rod 221 is formed on the depth control ring 23, the depth control ring 23 is sleeved on the guide rod 221, and an upper end surface of the depth control ring 23 is used for abutting against a lower end surface of the planting head 1 so as to limit the maximum drilling displacement of the planting head 1.

Specifically, it should be noted that the depth control ring 23 has a certain thickness, and is located on the upper end surface of the planting hole 211 after being sleeved on the guide rod 221 by the sleeve hole 231, and the middle part of the depth control ring 23 has the same through hole as the base 223. When the lower end surface of the guide assembly 100 abuts against the upper end surface of the depth control ring 23, the planter head 1 cannot move further, thereby controlling the drilling depth of the drill bit. The depth control rings 23 with different thicknesses can be selected or a plurality of depth control rings 23 can be overlapped according to actual situations. It will of course be appreciated that the depth control ring 23 may also be fitted over a guide bar 221 containing a base 223, and that the depth reached by the drill during implantation may be controlled in conjunction with the depth control ring 23 due to the controlled precision of the plane of the base 223.

To facilitate the intra-operative adjustment of the angle of the planter head 1, as shown in fig. 1, the guide assembly 100 in this embodiment comprises a sleeve-type slider 13 and a connecting rod 14;

the sleeve type slide blocks 13 are arranged in two and distributed on the left side and the right side of the planter head 1, guide holes are formed in the sleeve type slide blocks 13, and the lower end surface of the sleeve type slide blocks 13 is used for abutting against the upper end surface of the base 223 or the depth control ring 23;

the lower end of the planter head 2 is provided with a connecting column which is hollow and communicated with the drill bit hole 11; the two ends of the connecting rod 14 are fixedly connected with the corresponding sleeve type sliding blocks 13, and the middle part of the connecting rod 14 is rotatably sleeved on the connecting column;

the left and right sides of the planter head 1 are provided with arc-shaped sliding surfaces, the sliding surfaces are concentric with the drill bit hole 11, and the sleeve type sliding block 13 is slidably attached to the outer sides of the sliding surfaces.

Specifically, it should be noted that the front end of the planter head 1 has a circular structure, the sleeve-type slider 13 can rotate clockwise or counterclockwise along the sliding surface at the front end of the planter head 1 under the action of the connecting rod 14, and the center of rotation of the sleeve-type slider 13 is the same as the center of the drill hole 11. When the sleeve type slide block 13 is sleeved on the guide rod 221, the drill bit does not deviate when the planter head 1 is rotated, so that the positioning precision is kept unchanged. In order to facilitate the sleeve-type sliding block 13 to be sleeved on the guide rod 221, the lower end of the guide hole of the embodiment is a horn-shaped opening, and the upper end of the guide rod 221 is a truncated cone.

The planter head 1 in this embodiment can rotate around the drill hole 11 as a center of a circle, and the sleeve-type slide block 13 designed on the planter head 1 can use the central shaft of the drill as a rotation center to adapt to the placement of the handle 16 of the planter head 1 in planting operations with different dental level rows.

In order to limit the rotation range of the planter head 1 to protect the connecting rod 14 and the slider part from deformation, in this embodiment, a limiting frame 15 is arranged at the outer side of the planter head 1, two ends of the limiting frame are of a closed structure, the sleeve-type slider 13 is slidably arranged in the limiting frame, and the limiting frame is used for limiting the rotation angle of the sleeve-type slider 13; to facilitate the use of the planter head 1, a handle 16 is provided on the side of the planter head 1.

In this application, the base 21 is quick integrated into one piece of 3D printing technology, and base 223, guide bar 221, degree of depth control ring 23 and the planting aircraft nose 1 preparation material of supporting design are medical stainless steel, have the commonality, need batch production in advance, and the precision of being connected between guide bar 221 and the planting aircraft nose 1 is relevant with the accuracy of planting the operation. In the application process of the device, the size of the through hole of the depth control ring 23 or the size of the through hole on the base 223 are the same whether the guide rod 221 with the base 223 or the guide rod 221 without the base 223 is used, but the drill bit cannot rub with the inner wall of the through hole due to the guiding limitation of the guide rod 221, and the drill bit can rotate without resistance due to the fact that the diameter of the through hole is larger than that of the drill bit. The device can be used universally with any existing drill bit.

In summary, compared with the prior art, the invention has the following beneficial effects:

(1) The invention can adapt to the planting condition of anterior and posterior teeth missing, and the planting gap is limited by the opening degree, the guide rod 221 with the base 223 can not be used, the guide rods 221 with different lengths can be selected for the anterior tooth area and the posterior tooth area, and the guide rod 221 without the base 223 can also be selected, so that the flexibility is high and the applicability is good;

(2) The inner diameters of the planting holes 211, the through holes of the base 223 and the through holes of the depth control ring 23 are larger than the diameter of the drill bit, cooling water can enter the drill bit to play a role in cooling, and because of the constraint of the guide rod 221, the accuracy of the drill bit is not affected, and metal scraps generated by cutting the drill bit inner wall are not affected to heal tissues;

(3) When the sleeve type sliding block 13 moves linearly to the bottom of the guide rod 221, the whole length of the drill bit exposed out of the planter head 1 is positioned below the plane of the base 223, and the depth control rings 23 with different thicknesses can be selected according to the height from the alveolar bone of the plane of the base 223, the preset implantation depth and the length of the exposed drill bit to serve as a depth controller for planting operation;
